Connectors and jumpers
- J1, J2, J3, J4 - debug connectors. Duplicate ZIF socket connections (plus additional GND connections) and allow connecting external measurement equipment. Can also be used for testing ICs and circuits outside the ZIF socket.
- J5 - MCU programmer interface.
- J6 - USB port
- J7 - jumper shorting +5V to DUT power supply lines. Normally closed. Can be used for measuring IC current or for supplying the IC with external power.
CP2102N setup
To complete the hardware setup, CP2102N USB UART transceiver needs to be programmed with the following values:
- iManufacturer = mera400.pl
- iProduct = ictester
- MaxPower = 200mA
One possible way of programming it is to use this tool:
cp2102 -p "ictester" -m "mera400.pl" -x 200
You can also use one of the tools provided by the manufacturer - Silicon Labs.
This step is not required, although without it no device autodetection will be possible.

Where can I download the Ictester KiCad files?
From the jakubfi/ictester repository on GitHub, at the commit this page was made from: the board is hw/ictester.kicad_pcb and its schematic hw/ictester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ictester design in my own project?
Its repository states no licence, so its author keeps all rights: ask jakubfi before reusing the design.
